Yes, but its hard to expalin unless you've tasted both.

Here are brief Wiki extracts:

"Marmite is a brand of savoury food spread from the United Kingdom, based on yeast extract invented by German scientist Justus von Liebig. It is made from by-products of beer brewing (see Lees (fermentation)) and is currently produced by British company Unilever. https://en.wikipedia.org/wiki/Marmite ..."

"Vegemite is a thick, dark brown Australian food spread made from leftover brewers' yeast extract with various vegetable and spice additives. It was developed by Cyril Callister in Melbourne, Victoria in 1922. ..."

A spread for sandwiches, toast, crumpets and cracker biscuits as well as a filling for pastries, Vegemite is similar to British Marmite, New Zealand Marmite, Australian Promite, MightyMite, AussieMite, OzEmite, German Vitam-R, and Swiss Cenovis. https://en.wikipedia.org/wiki/Vegemite."

Special note to Americans: Vegemite is owned by Kraft, a US multinational. So you're to blame for foisting it on the world!

Not anymore. Bega bought Vegemite from Mondelez, so it's Aussie through and through again.

OK, right. Thanks. So the label on my jar is out of date.

That's one for books, but as far as I recall Kraft was there from the outset in the 1920s (so it was really always US-owned until recently).

Edit: just checked the low-salt version (both are used here—it's the smaller jar) and the label is different. Never noticed that until now.
